Anchorage, AK 99507
Attention: Debbie Wockenfuss
Subject: Uplands Subdivision, Phase 3
Lots 1 through 7
Dear Debbie:
The owner of Tract 2, Uplands Subdivision intends to subdivide the tract into 7 lots and rename
the subdivision Uplands Subdivision, Phase 3. The property in general is sloped to the southwest
at grades ranging from 15% up to around 50%. Most of the area is in the 10-20% range, with a
few portions steeper than 25%. There are also some areas where, for short distances, the slopes are
greater than 46%. Lot sizes are all greater than 40,000 S.F. each. Surface drainage is primarily
from north to south and toward the southwest at the west boundary. No standing water has been
observed on the property and no drainage issues are present. Septic systems will not be affected
by storm water runoff.
Test holes were dug in late October of 2018. Two test holes were placed on each lot in areas that
seemed appropriate for septic locations. Monitoring tubes were placed in the test holes and
groundwater monitored over time. The test holes were completed to 16' in most areas. No bedrock
or, impervious soil lenses were encountered. No groundwater was encountered in any of the test
holes except on Lot 3 where groundwater was monitored at 6' below the surface. Soils were fairly
uniform in the area, consisting mostly of silty, sandy gravel. Percolation benches were constructed
between 4-6' below the ground surface in each test hole. The percolation cavity in each bench was
prepared and presoaked in accordance with municipal requirements. Again, results were very
uniform in the area, with almost all perk tests results falling under 20 min./in. Individual test results
are included on the attached test hole logs.
A study of the nitrate content in wells on the surrounding lots was completed. The results of this
study are summarized below:

11/29/07
4.96 mg/liter
Preuss No. 4, Block 9, Lot 10
5/16/00
1.34 mg/liter
Septic system reserve areas were calculated for each lot based on percolation test data and Table
7 of the Municipal Code. Reserve areas range in size from 10,000 S.F. on two lots to 12,000
square feet on Lot 6. Slopes in excess of 46% are found within 100' of the boundaries of these
reserve areas. These slopes flatten after a drop of only 10' to 16' in the case of Lots 6 and 7. The
underlying soils on Lots 1, 6 and 7 are very absorbent withpercolation rates ranging from 1 to 5
minutes per inch. Septic effluent is expected to be absorbed vertically with very little horizontal
migration. In addition, natural vegetation will be retained or erosion control measures taken, and
the distribution pipe placed at a minimum of 3' below the existing ground surface.
Sufficient surface area could not be found for reserve areas for Lots 2 through 5 due to the
proximity of slopes greater than 46%. Individual septic absorption sites were designed on these
lots that meet the separation distance requirements. Lots 3, 4 and 5 will require placement of
Category III septic systems. Category III septic systems require a minimum of 35' separation
from slopes greater than 25%. Lot 2 will have a conventional septic system designed to meet the
steep slope criteria of the Municipal Code including vertical separation distances measured from
the up -gradient side of the field, trenches 5' or narrower, natural vegetation retained or erosion
control measures taken, and the distribution pipe placed sufficiently deep. Under these guidelines,
these small sections of steeper slopes are appropriate for development of septic system.
Slopes greater than 46% are found less than 100' from the edge of the absorption trenches.. but the
slope drops for a minimum of 20' before flattening to a much shallower slope. The subsurface
soils on Lot 2 are very absorbent with percolation rates of l to 5 minutes per inch. No horizontal
migration of effluent is expected. The Site Plans, System Profiles and Design Test Hole for these
lots are attached for your review.
The absorption trench locations for Lots 2, 3, 4 and 5 will be placed on the final plat. A plat note
will be required concerning the septic system locations. The recommended notes are as follows:
1. Category III Advanced Wastewater Treatment Systems approved by the Municipality of
Anchorage is required on Lots 3,4 and 5. The maximum number of bedrooms for a house
on Lots 2 and 3 is limited to four. No driveways, parking areas or structures may be
placed over the absorption trench locations.
2. Alternate locations for wastewater disposal reserved areas may. be used if approved by
the Municipality. In which case, the locations shown hereon shall move to the new
locations and an amended plat shall be filed with the State Recorder's Office detailing the
changes.
Please review the attached information and advise if further information is required.
Sincerely,
Michael E. Anderson, P.E.
